DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 3 As shown, the utility model provides a cuff buttonhole machine, including a buttonhole machine body 1, a buttonhole machine base 2 and a positioning mechanism 3, a needle 7 which can move up and down is provided below the head of the buttonhole machine body 1, the buttonhole machine body 1 is arranged on the buttonhole machine base 2, the buttonhole machine base 2 is provided with a buttonhole hole 8 below the needle 7, a slide groove 4 is provided on the side of the buttonhole machine base 2 away from the buttonhole hole 8, the positioning mechanism 3 includes a slide bar 31 which moves along the slide groove 4, a protruding slide block 32 is provided on the slide bar 31, a movable slide plate 33 is provided on the slide block 32, the moving direction of the slide plate 33 is perpendicular to the moving direction of the slide bar 31, a clamping plate group 34 is provided at the bottom of the slide plate 33, and the clamping plate group 34 is provided on both sides of the needle 7.

[0027] When the needle 7 carries the thread end downwards for sewing, the needle 7 passes through the fabric downwards and is inserted into the buttonhole hole 8, and then moves upwards with the thread end to complete a buttonhole unit action. The entire buttonhole process consists of a plurality of reciprocating buttonhole unit actions.

[0028] The clamping plate group 34 is used to clamp the cuffs of clothing and fix the two ends of the cuffs. Due to the clamping function, no matter what fabric the cuffs are made of or how thick they are, the clamping plate group 34 can accurately clamp the cuff fabric and position the cuffs. Even when the thickness of the cuffs is different, the clamping plate group 34 can quickly clamp cuffs of different thicknesses, and the operation is simple.

[0029] The moving direction of the slide plate 33 is perpendicular to the moving direction of the slide bar 31. Specifically, when the slide plate 33 moves forward and backward along the length direction of the buttonhole machine base 2, the slide bar 31 moves left and right along the width direction of the buttonhole machine base 2, and the clamping plate group 34 can move forward and backward and left and right with the clamping cuff.

[0030] When the cuff is buttonholed, the clamping plate group 34 will drive the cuff to move forward and backward and left and right under the action of the positioning mechanism 3 according to the system settings of the control panel. During the buttonhole process, the needle 7 only performs up and down locking actions, and the cuff moves under the needle 7 to finally complete the buttonhole action.

[0031] When multiple buttonholes need to be processed on the cuff fabric, the system only needs to adjust the positioning mechanism 3 to drive the clamping plate group 34 to move to the next buttonhole position and perform the buttonhole action.
